CeFindNextDatabaseEx

This function retrieves the next database in an enumeration context. A remote application interface (RAPI) version of this function exists, and it is also named CeFindNextDatabaseEx.

CEOID CeFindNextDatabaseEx( 
HANDLE hEnum,
PCEGUID pceguid);

Parameters

• hEnum
  [in] Handle returned from CeFindFirstDatabaseEx.
• pceguid
  [in] Pointer to the CEGUID that contains the globally unique identifier of a mounted database.

Return Values

A valid CEOID indicates success. Zero indicates failure or a lack of additional databases. Call GetLastError to get the extended error information. Possible values for GetLastError include the following:

• ERROR_NO_MORE_ITEMS
  There are no more databases to enumerate.
• ERROR_KEY_DELETED
  A database was deleted during enumeration.

Remarks

Note   Earlier versions (2.12 and prior) of Windows CE assigned OIDs to objects in other file systems, such as the FAT file system. These OIDs were guaranteed to be unique within a volume, but not across multiple volumes. Effective with version 3.0, only objects in the object store have valid, unique OIDs and the object store is the only volume that can return an object identifier.

To find all matching databases, CeFindNextDatabaseEx is called in a loop until 0 is returned. If a database is deleted during an enumeration, CeFindNextDatabaseEx fails and returns error ERROR_KEY_DELETED. If this error occurs, you must restart the enumeration with a call to CeFindFirstDatabaseEx. When enumeration is complete, the hEnum handle must be closed by calling the CloseHandle function.

Requirements

Note   This API is part of the complete Windows CE OS package as provided by Microsoft. The functionality of a particular platform is determined by the original equipment manufacturer (OEM) and some devices may not support this API.
